Spontaneous Mutations - Mutations which occur under natural conditions are called spontaneous mutations. It should be noted that some spontaneous mutations arise by the action of mutagens present in the environment.

These mutagens include cosmic radiation, radioactive compounds, heat, and such natural occurring base analogues like caffeine.

These will be considered under 'induced mutations' as they are external agents bringing about mutations. Truly spontaneous mutations that will be dealt with here are those arising from tautomerism.
